Linking Customer Needs of Refractory Suppliers with Technological Requirements on the Refractories
A tool to link customer needs with technological requirements is a method called House of Quality (HOQ). In this study a planning matrix-HOQ for refractories applied in steel ingot casting is developed. Of the technological requirements thermal shock, erosion, impact and corrosion resistance, the thermal shock resistance has the highest impact on the application behaviour. Nevertheless, by optimising the corrosion resistance good results can be obtained faster. Thus, the method proved to be able to identify not only importances of the requirements but also an order in which to address their development.
